Trinitarians often claim Matthew 28:19 supports their belief in a trinity. But this verse in no way affirms the trinity doctrine which states that the Father, Son and Holy Spirit are three co-equal, co-eternal beings that make up one God.

Nobody denies there is the Father, Son and the Holy Spirit.

This verse refers to three entities but never says they are one and says nothing about their personality. It does not say they are three beings, it does not say they are three in one or one in three, it does not say these three are the Godhead, it does not say these three are a trinity, it does not say these three are co-equal or co-eternal beings, it does not say that these three are all God, and yet some draw the conclusion that this supports their belief in the trinity or that the Holy Spirit is another being which is clearly not so. It is just another very bad assumption.
